Abstract

A combination for administration to a mammal which combination employs a therapeutically effective amount of a medicinal and/or therapeutic agent to treat a disease or condition and an amount of hyaluronic acid and/or salts thereof and/or homologues, analogues, derivatives, complexes, esters, fragments and subunits of hyaluronic acid sufficient to facilitate the agent's penetration through the tissue (including scar tissue) at the site to be treated, through the cell membranes into the individual cells to be treated.

Claims

exact text as granted — not AI-modified
The Embodiments of the invention in which an Exclusive Property or Privilege is claimed are as follows: 
     
       1. A method of treating a condition or disease in a human involving tissue selected from the group consisting of underperfused tissue and pathological tissue which will benefit from the treatment by the administration of an agent selected from the group consisting of a medicinal agent and a therapeutic agent and combinations thereof, which is suitable for treating said tissue, the method comprising administering to the human a therapeutically effective dosage amount of a pharmaceutical composition comprising a therapeutically effective amount of the agent to treat the disease or condition involving tissue selected from the group consisting of underperfused tissue and pathological tissue, and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof sufficient to facilitate the transport and penetration of the agent through the tissue at a site to be treated through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg and less than 3000 mg. 
     
     
       2. A dosage amount of a pharmaceutical composition in a suitable pharmaceutically acceptable excipient for treating infection involving underperfused tissue and pathological tissue in humans, said dosage amount comprising a therapeutically effective amount of an agent selected from the group consisting of antibiotics, antibacterials, antimicrobials and combinations thereof with or without ascorbic acid and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg. 
     
     
       3. The dosage amount of claim 2 wherein the form of hyaluronic acid is sodium hyaluronate. 
     
     
       4. A dosage amount of a pharmaceutical composition in a suitable pharmaceutically acceptable excipient for treating infections surrounding implants involving underperfused tissue and pathological tissue in a patient, said dosage amount comprising a therapeutically effective amount of an antibiotic agent for treating the infected tissue surrounding the implant and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport and penetration of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg. and less than 3000 mg. 
     
     
       5. A method of treating infection involving underperfused tissue and pathological tissue in humans, the method comprising the administration of a therapeutically effective amount of an agent selected from the group consisting of antibiotics, antibacterials, antimicrobials and combinations thereof with or without ascorbic acid and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport and penetration of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg and less than 3000 mg. 
     
     
       6. A method of treating infections surrounding implants involving underperfused tissue and pathological tissue in a patient, the method comprising the administration of a therapeutically effective amount of an antibiotic for the infected tissue surrounding the implant and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport and penetration of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg and less than 3000 mg. 
     
     
       7. The method of claim 6 wherein the form of hyaluronic acid is sodium hyaluronate. 
     
     
       8. A dosage amount of a pharmaceutical composition in a suitable pharmaceutically acceptable excipient for the prevention of topical infection involving underperfused tissue and pathological tissue in humans, said dosage amount comprising an effective amount of an anti-metabolite agent for preventing topical infection and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport and penetration of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg and less than 3000 mg. 
     
     
       9. The dosage amount of claim 8 wherein the form of hyaluronic acid is sodium hyaluronate. 
     
     
       10. A method of (preventing) treating a topical infection resulting from a condition or disease in a human involving underperfused tissue and pathological tissue in humans, the method comprising the administration of an effective amount of an anti-metabolite agent and a sufficient amount of a form of hyaluronic acid selected from the group consisting of hyaluronic acid and its non-toxic salts and combinations thereof to facilitate the transport and penetration of the agent at a site to be treated by the agents passing through the tissue through the cell membranes into the individual cells to be treated wherein the molecular weight of the form of hyaluronic acid is in the range of 150,000 to 750,000 daltons, and said amount of the form of hyaluronic acid is sufficient to provide a dosage greater than 10 mg and less than 3000 mg. 
     
     
       11. The method of claim 10 wherein the form of hyaluronic acid is sodium hyaluronate.
